The MMX Magnetic Differential Plug Seal Kit supplies five replacement crush seals for MMX magnetic differential plugs. A crush seal is a single-use item by design, and this pack covers five oil changes at a cost that makes reusing an old one pointless.


Why A Crush Seal Is Not Reusable

A crush seal works by deforming permanently as the plug is torqued, filling the machining marks on the housing face. Once deformed it cannot do the same job twice, and a reused seal is the single most common cause of a slow weep from a differential drain or fill plug. Fitting a fresh one every time is the correct approach and takes no extra effort.


Buy Once, Cover Five Services

A differential oil change is not a frequent job, which is exactly why the right seal is never to hand when it is due. A pack of five sitting in the toolbox removes that problem for the foreseeable future.

Frequently Asked Questions

Is the magnetic plug included?
No. This kit contains five replacement seals only.

Can a seal be reused if it looks undamaged?
It should not be. A crush seal deforms permanently on first use and will not seal reliably a second time.


The Right Consumable For The Job

A five-pence seal is what stands between a clean differential and an oil weep down the subframe. MMX supplies them in fives so the right one is always in the toolbox. Stocked by R44 Performance alongside the full MMX maintenance range.
